Copernicus and the trial of Galileo

Geocentric was the first theory about the earth. Aristole & Ptolemy believed that the earth was the center of the universe. It was said that it was the center of the universe until Copernicus presented a mathematical model of the heliocentric system. The heliocentric model was that the sun was the center of the universe, not the earth. Heliocentric was in the scientific revolution because that is when Kepler did more observations about it. He believed the same thing as Copernicus. When he figured out that it was right. Everyone started to belive him. The sun was the center of the universe.
